Problems solved by technology

[0004] The disadvantage of the method for users to access the DDN network in the above-mentioned prior art is: due to the limitation of the interface of the terminal equipment, the distance of the user line is only tens of meters, so in some places far away from the DDN network, the user cannot use this method to connect to the DDN network. into the DDN network
If the DDN network is extended to remote users, it will increase a lot of cost and bring a big burden to the operator

Embodiment Construction

[0035] The present invention provides a device and method for providing multi-subrate access for users. The core of the present invention is: using MTA equipment and ISDN BRA (basic rate access or interface) port to realize the DDN access that can not only meet the user's demand for multiple rates, but also realize the long-distance user.

[0036] The present invention first proposes a device that provides multi-subrate access for users, that is, MTA device, which has functions such as BRA physical layer, layer 2, and layer 3 of ISDN, and is an ISDN terminal device. The structure diagram of the device is shown in figure 1 As shown, the following modules are included:

[0037] Sub-rate interface module: used to provide clients with various sub-rate interfaces less than or equal to 64Kbits / s, specifically V.35(64K), V.24(19.2K), V.24(9.6K), V.24(9.6K), .24 (4.8K), V.24 (2.4K) 5 kinds of rate interface. Receive various user messages transmitted by the user through one of the i...

Abstract

The invention supplies a MTA device and a method to supply plural sub-ratio accessing for user. The invention contains BRA physical layer, 2 layer, and 3 layer function that is an ISDN terminal device including sub-ratio interface module, U interface module and information process module. The method includes the following steps: user sending user message to MTA device through the ratio supplied by MTA device; the MTA device transmitting the user information to BRA of ISDN; the BRA sending the user information to network host. The invention could satisfy accessing remote user accessing to DDN network under multi sub-ratio.

Description

technical field [0001] The invention relates to the communication field, in particular to a device and a method for providing multi-subrate access for users. Background technique [0002] DDN (Digital Data Network, Digital Data Network) is a communication network that uses digital transmission channels to transmit data signals. Special purpose circuits and other new services. [0003] In the actual use of DDN, users need to access the DDN network at various rates. In the prior art, a method for users to access the DDN network is: the user directly connects to the DDN network through terminal equipment provided by some manufacturers. The terminal device can provide users with various sub-rate accesses less than 64K according to the different needs of different users. [0004] The disadvantage of the method for users to access the DDN network in the above-mentioned prior art is: due to the limitation of the interface of the terminal equipment, the distance of the user line i...
